If a gas occupies a volume of .06 L at 250 K, what will it’s volume be at 325 K?

Explanation:

Explanation:

If you treat it as an ideal gas, then  

P

V

=

n

R

T

where P is pressure, V is volume, n is number of moles, R is the gas constant and T is temperature in K.

If you assume pressure is constant, and we know that the amount of substance will remain constant, and of course the gas constant is a constant, then  

V

varies directly with  

T

. So for the two temperatures you can say:

V

1

.

T

1

=

V

2

.

T

2

V

2

=

V

1

.

T

1

T

2

T

2

, the higher of the two temperatures, will be 273 K and  

T

1

will be 20 degrees lower, so 253 K.

Now plug in the numbers:

V

2

=

3

.

253

273

=

2.78

litres.

explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
